Answer:
your answer is right its 2.5 x 10^-9
Step-by-step explanation:
70
to find the answer do 60+x / 2 =65
Solver for x
multiply 2 on both sides to get 130
60+x=130
x=70
Answer:
y = - 0.5x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 4, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line
m =
=
=
= - 0.5
The line crosses the y- axis at (0, 0 ) ⇒ c = 0
y = - 0.5x + 0 . that is
y = - 0.5x
